Title:
METHOD FOR PREPARING FLAKE-TYPE SILVER POWDER BY USING AGGLOMERATED SILVER POWDER
Document Type and Number:
WIPO Patent Application WO/2018/066723
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a flake-type silver powder, comprising a flaking step (S2) of using an agglomerated silver powder as a material powder so as to obtain a powder flaked by means of milling through beads, wherein the agglomerated silver powder is obtained by agglomerating silver particles having a diameter of 0.5-2.0 μm and has an average diameter of 5.0-20.0 μm and a specific surface area of 0.1-0.6 m2/g. The present invention can provide a method for preparing a flake-type silver powder having a small thickness and a large average diameter, that is, having a high aspect ratio (diameter/thickness), the method enabling: preparation with low preparation costs by using universal milling facilities and beads since an agglomerated powder instead of a spherical powder is used as a material powder; and particle size to be controlled while minimizing the compression between flake-type silver powders to be prepared since the particle size of the agglomerated powder is controlled.
